MAGNETIC EXTRACTING AND SEPARATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,446, dated January 21, 1896.

Application filed February 27, 1895. Serial No. 539,937. (No model.)

To all whom it may concern Be it known that we, FRANK JAMES BAR- NARI), JOHN CHAELEs MOORE, and JOHN DET- WILER ATKINSON, residing at Seattle, in the county of King and State of \Vashington, have inventeda new and useful Magnetic EX- tracting and Separating Machine, of which the following is a full, clear, and exact description.

Our invention relates to the extracting and separating of magnetic particles or substances from mixed masses of magnetic and non-magnetic particles and substances by the action of a magnet or plurality of magnets inclosed in a shield or casing of copper or other non-magnetic material fastened, down wardly projecting, to a stationary plate or frame in combination with'a belt having on its outer surface strips, cleats or conveyers extending crosswise the width of the belt, which belt moves beneath the magnet or plurality of magnets, between the same and the sluice on pulleys placed at each end of the main frame and extends over and across a channel or sluice in which a mixed mass of magnetic and non-magnetic particles is brought within the magnetic held by the action of flowing water or other liquids, and said magnet or plurality of magnets being fastened to a frame and extending across a sluice or channel and being within the traveling belt the magnets attract and draw up such magnetic particles to and against the belt, and the belt, aided by the strips or cleats, carries the magnetic particles so attracted beyond the magnetic field and outside the channel orsluice. \Ve attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is-a perspective view of the entire machine with parts represented as broken away in order to more fully illustrate its mechanism. Fig. 2 is an enlarged horizontal crosssection taken in the line 1 2 in Fig. 1. Fig. 3 is a partial end View showing the manner in which power is applied. Fig. 4 is a detail of the belt and frame adjusting arrangement.

Similar letters refer to similar parts throu ghout the general views.

The main frame A A A supports the adjustable frame B B, upon the ends of which journal-boxes are placed carrying the pulleys O 0. About midway between the pulleys and suspended by means of cross-pieces e e, which are supported by the main frame A A A, is a magnet or plurality of magnets D inclosed within a shield or casing E made of copper or other non-magnetic material, the upper part of which is flange-shaped, so that it may be fastened to the plate or cover F.

a a are air-holes to insure a continuous circulation of air around the magnets to prevent them from becoming overheat-ed. The plate or cover F also acts as a means by which the magnets are suspended. This is accomplished by means of screws b b, which are driven into the center or core of each magnet.

G' is a belt of any suitable material which passes around pulleys C C and has fastened upon its outer surface strips or cleats of nonmagnetic material which extend its entire width. These strips or cleats may be made any shape. As the pulleys revolve, the belt G passes under and comes in contact with the shield or casing E of the magnets D and the strips or cleats m act as conveyers of the magnetic particles or substances, which, coming in contact with the belt G, adhere thereto until conveyed beyond the magnetic field outside the channel or sluice I, when by their own gravity they become detached and fall into proper receptacles. The belt G is kept in contact with the bottom of the shield or casing E by means of sliding journal-boxes H H, placed at one end of the adjustable frame B B and carrying between them one of the pulleys O. The lower part of these boxes projects beyond the main body to allow bands or straps (Z (Z to pass over the same and around the adjustable frame B B, thus forming clamps which, by means of set-screwsf f, are intended to hold the boxes in place after adjustment. The adjustment is accomplished by loosening set-screws f f, which allow said boxes to slide freely upon the adjustingframe B B by means of hand-screws g g.

The object of the above-mentioned adj ustable frame is to allow the belt G to be tilted in any desired direction or to keep said belt in a perfectly horizontal position, the main frame A A A remaining rigid. The frame B B is adjusted by loosening bolts 72, h and bolts passing through a slot in the inai-n frame A A A.

The magnet or plurality of magnets D may be permanent magnets, but preferably electromagnets, in which case-proper and suitable insulations and connections with a dynamo or other source of electrical energy must be made. Power is applied by means of pulley K or any other convenient manner as may seem necessary for the successful Working of the machine.

Having thus fully described our invention, We claim as new and desireto secure by Letters Patent 1. In a magnetic separator, the combination of a frame, a suitable non-magnetic casing having a suitable top by which the easing is secured to said frame, and a number of 'perforations in the casing for permitting a freecirculation of air a number of magnets secured to said to'p'an'd projecting downwardly within the casing, and a cO-nVe'yer belt passing beneath said casing, substantially as and for the purpose set forth.

2. The combination of a suitable sluice, a frame located oversaid sluice, and carrying a supplemental frame adjustable in a Vertical and angular direction therein, a pair of drums mounted in said adjustable frame, one of Which is adjustable in a horizontal direction, a conveyer belt passing around said drums, anon-magnetic casing provided With a cover by which it is secured to the supplemental frame and between the belt, and a number of magnets secured to the cover and projecting down into the casing substantially as shown and described.
